| 摘要 |
Apparatus is provided for controlling a thickness (h) of a film of development fluid within a development nip of a liquid ink development (LID) machine. The apparatus includes a first moveable member having a first velocity (V1) and a path of movement defining a radius of curvature (R) for forming a long development nip. It also includes a second moveable member mounted partially about the first moveable member for forming the long development nip, and having a second velocity (V2) as well as a tension (T). The apparatus further includes a mechanism for introducing into the long development nip liquid development fluid having a viscosity (mu), and a programmed controller connected to the first moveable member and the second moveable member, for controlling the first velocity (V1), the second velocity (V2), and the tension (T) so that h=K1R{K2 mu(V1+V2)]/T}⅔, where K1 and K2 are each a constant.
